Liquid Tension Experiment!
It’s got Portnoy, Petrucci and Rudess from Dream Theater and Tony Levin who is brilliant on the Chapman Stick. It’s more or less entirely instrumental.
They have made 2 albums (both self titled, the second is called LTE2), the first is the better album, but my favorite song by them is called Acid Rain, the opener of the second album.
Although yea I like a lot of instrumental music besides LTE. Who has heard the instrumental piece called ‘Woodpecker from Mars’ by Faith No More? I reckon it is great (-:
